Is a little bulge in the lower stomach normal?

I have been working out, and I lost a couple pounds, but my lower stomach is still a little bigger than my ribcage. It feels muscular (with a little fat over it) but I can't get it completely flat. At my lowest weight last year, my lower stomach was a little bigger than the top also, so its pretty normal for me. Is it normal in a lot of ppl or am i bloated for some reason?
